^^^True. And something that really is better now, may not be better once we have more information. Think about the drugs doctors gave pregnant women to prevent miscarriages (a good thing) that caused birth defects in the babies (a bad thing), for example.
But overall, I think that many of the problems we face in modern societies, like how to care for large elderly populations, or over consumption of resources, are, while serious, much better than the problems all societies faced in the past.
Like how to keep the witches from killing every single person in town with plague, how to keep witches from killing all the babies, how not to have a baby every year from age 12 until you die in childbirth, how to survive the annual famine periods between planting and harvest and during the winter, how to have enough slaves to work the farm so everyone can eat, how not become a slave, how not to be murdered by your slaves....
Progress is real. Human survival to the tune of 7+ billion people, most of whom will not die of starvation, has been a fantastic success. Now we just have to make sure we don't screw it up.
